Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned ovachiever/droid-tings at 7acd12a754.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill enables AI agents to execute custom JavaScript code directly within the n8n automation platform. It allows for complex data transformations, logic branching, and API interactions that go beyond standard node capabilities.

When to use it

  • You need to perform advanced string manipulation or regex parsing on workflow data.
  • Your automation requires dynamic calculations based on variable inputs from previous nodes.
  • You want to integrate with external APIs using specific authentication methods not covered by native n8n nodes.
  • You need to debug or prototype logic quickly without building a full custom node.

Key capabilities

  • Executes arbitrary JavaScript code within the n8n environment.
  • Processes and transforms JSON data structures passed between workflow nodes.
  • Enables complex conditional logic and error handling inside workflows.
  • Facilitates direct interaction with external services via HTTP requests.

Example prompts

  • "Write a JavaScript node in n8n to parse a CSV string into a JSON array."
  • "Create an automation that calculates tax based on dynamic regional rates using custom code."
  • "Set up a workflow step to validate email formats and extract domains using regex."

Tips & gotchas

Ensure you have basic JavaScript knowledge, as errors in the code will halt the entire workflow execution. Test logic thoroughly in a sandbox environment before deploying to production workflows to prevent data loss.
